Default The most rugged power electrolytic capacitor

Hi,
Seem be there are many good power cap:
-Rifa PEH169
-Felsic 037/039
-F&T screw
-ROE EYL, EYM, EYP...
-BHC ALSxx
-Philips/BC screw
-Siemens/Epcos Sikorel
... More?
Can anyone give me suggest: which is the winner of long life and condition tolerating?
I don't care much about leaded/snap-in since they are only good for PCB mount and cannot dissipate much heat through their small leads.
Any comments are welcome!

So you're looking for a 105C range with at least 10,000 hrs at rated operating conditions (ie. temp and ripple current).

I need something around 10000-15000uF, 75-100V.
10000 hrs at maximum rating is good, but more are better, of course.
I have seen some people torn the plastic sleeve and wrap the naked cap with handmade heatsink from alum sheets. So I search for more effective heatsinking, I found that Mundorf HC and F&T GW are designed to attach to heatsink. Mundorf are too expensive so let them out the table. May the F&T GW is the way to go?
PEH169 was told like a rock but they spec are no better than Felsic. Any suggestion?
ROE, Philips, BHC seem only NOS or used now. Sikorel are for fast pulse (advantage?)

Use 2-4 caps in parallel instead of chasing ONE perfect cap.

Or just get some Epcos B41550, and I don’t think the mention of them being capable of pulsed applications makes them in a special category, they are just great parts.
They’re made with several windings like you would have with several smaller parts in parallel together, probably have some damping characteristics too that makes them better at pulsed applications.

Yes, I want to parellel 2 cap to get about 30000uF, 4 maybe too hard to fit in my case.
